Embodiment 1

[0031] We weigh each component of the following parts by weight:

[0032]

[0033] Then do the following:

[0034] After mixing the above-mentioned components weighed, they are kneaded in a high-speed mixer through a conveying system;

[0035] After kneading, the components are sent to an internal mixer (closed rubber mixer) for internal mixing;

[0036] The components after internal mixing are transported into the open mixer (open rubber mixer) for open mixing;

[0037] After the refining, the components enter the planetary extruder and then extruded by the planetary system;

[0038] The components of the planetary extrusion are calendered into a sheet film through a calender

[0039] Extraction, cooling, and winding of the calendered film to obtain the finished product 1

Embodiment 2

[0041] We weigh each component of the following parts by weight:

[0042]

[0043] Then we carry out operation with the operation step in embodiment 1 to above-mentioned each component, obtain finished product 2.

Embodiment 3

[0045] We weigh each component of the following parts by weight:

[0046]

[0047]

[0048] Then we carry out operation with the operation step among the embodiment 1 to above-mentioned each component, and its difference is, in the embodiment 3, also comprise composite section, it comprises the following steps:

[0049] a. Select fabric as the base material for unwinding (according to actual needs, it can also be other base materials);

[0050] b. Then preheat the fabric substrate;

[0051] c. After preheating, introduce the base cloth for compounding;

[0052] d. At this time, it is pasted with the components calendered in step 5;

[0053] e. Then continue to operate with step 6 to carry out extraction, cooling, and winding to obtain the finished product 3.

Abstract

The invention provides a nano-silver PVC (polyvinyl chloride) lamellar membrane and a preparation method of the lamellar membrane; the nano-silver PVC lamellar membrane is prepared by fully mixing nano-silver with each component of PVC lamellar membrane, mixing and modifying, and then carrying out the processes of rubber milling, rolling and the like; the nano-silver PVC lamellar membrane has excellent sterilizing property, and thus the nano-silver PVC lamellar membrane can be widely used for industries such as medical treatment, food package and the like conveniently; in addition, the invention further discloses a method for preparing the nano-silver PVC lamellar membrane with two-layer or multi-layer composite structure; by adopting of the method, the practicability of the nano-silver PVC lamellar membrane can be improved and the application scope is extended.

Description

technical field [0001] The invention relates to the field of antibacterial materials, in particular to a nano-silver PVC sheet film and a preparation method thereof. Background technique [0002] PVC is Polyvinylchlorid, the main component is polyvinyl chloride, PVC film is widely used in building materials, packaging and pharmaceutical industries, there are two very important reasons, one is due to the unique properties of PVC film, including rainproof, fire resistance , antistatic, easy to form, etc. The second is the characteristics of low input and high output of PVC film. In view of the global spread of SARS virus, avian influenza, and H1N1 influenza virus in recent years, and the increasing number of infected people, the research and development and rapid development of antibacterial materials in the fields of military supplies, medical treatment, daily use, and food packaging have been promoted. Similarly, for the antibacterial functionalization of plastic hot-melt c...
